IMPROVEMENT lN DETACHABLE LINKS.

Specification forming part of Letters Patent No. 187,927, dated February27, 1877; application filed October 24, 1876.

To all whom it may concern:

Be it known that I, SAMUEL STEVENS, of Alleyton, in the county ofNewaygo and State of Michigan, have invented certain new and usefulImprovements in a Detachable Link; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing, and to the letters of referencemarked thereon, which form part of this specification.

The nature of my invention consists in the construction and arrangementof a detachable link, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a side view of the link. Fig. 2 is a perspective view of thesame.

My detachable link is formed in two pieces pivoted together. Onepiececonsists of a round or oval bar, A, with a semicircular hook, B, at eachend and a post, 0, in the center between them. On top of the post 0 ispivoted the piece I), which is of such form and size as to close thespace between the ends of the two hooks B B. At one end of the piece Dis formed a projecting curved flange, d,

'which flange, when the link is closed, fits in a recess, b, made in theside of oneof the hooks B.

Thus, when the link is closed in the chain, it cannot becomeaccidentally detached, while,

when desired, the chain can be slacked and the link quickly detached.

The part 1) of my link is made round or oval, as shown, with theexception of the projecting flange or hook at, and said part D ispivoted directly on the end of the center-post 0, but when in use thereis no strain upon the pivot, neither is there any strain on the part D,as the adjoining links of the chain have their bearings entirely uponthe hooks B B at the ends of the bar A. This bar A, with its hooks, maybe made of any desired size, to have the required strength, while thepart D need not be so very strong.

I am fully aware that detachable links made in two parts, pivotedtogether, are not new; hence I do not claim such, broadly, as being myinvention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the bar A, with centerpost G and semicircular hook Bat each end, and the part D, pivoted on the center-post, and provided atone end with the projecting curved flange d, to fit in a recess, b, onone side of one of the hooks B, and straight at the other end,substantially as set forth.

In testimony that I claim the. foregoing as my own I affix my signaturein presence of two witnesses.

SAMUEL STEVENS.
